According to a new study, injecting protein from younger mice blood can be key to "getting" in older mice.
Scientists say that the protein, called eNAMPT, is productive in young mice and that older rodents are kept healthier and longer lasting.
Cognitive function has been improved in older mice with injected protein, with better sleep quality and almost 20 percent longer life span.
In humans it is the same as the extension of life span from 79 to 91 years.
A team from the University of Washington Medical School at St. Louise, Missouri, said the findings suggest that this method could be a secret in combating aging-related and anti-aging methods for people.
Protein is an enzyme called eNAMPT, which plays a role in cell energy production.
However, as the body is old, cells lose their energy production efficiency called NAD.
"We believe the body has so many redundant systems to maintain the correct values of NAD because it is so important," said Dr. Shin-ichiro Imai, professor of development biology at Washington University.
"Knowing that NAD with inevitably decreases with many years, many researchers are interested in finding anti-aging measures that can maintain NAD levels with the years."
For a study published in the journal Cell Metabolism, a team of older mice gave a concentrated eNAMPT from younger mice and other saline.
Mice in the saline receiving group all died within about 2.4 years, while the eNAMPT mice died within about 2.8 years.
This means that the life of the mice in the protein group was about 16 percent longer than in the control group.
Older mice with higher concentrations of this blood component also had better sleep quality, improved cognitive function in memory tests, and moved more on the wheels in their cages.
"We found a brand new way of healthy aging," Dr. Imai.
"It is important to note that eNAMPT can be taken from the blood of young mice and applied to older mice and find that older mice have a significant improvement in their health – including increased physical activity and a better sleep."
The path is similar to that of the Harvard University geneticist. David Sinclair, who claims to live longer by taking Elysium, a molecule known as NAD Booster. It has been found to improve health and extend life to mice.
Dr. Imai and his team believe that this is the reason why we are getting faster digestion of hypothalamic-related proteins.
The hypothalamus is a brain area that is known to be important for social behavior and hormone production. This protein is largely regulated.
It has recently been discovered that stem cells in the hypothalamus control the aging process of the body.
As the level of this key protein decreases during aging, researchers believe that the hypothalamus does not work that well, which shortens life expectancy.
For future research, the team wants to investigate whether the low level of eNAMPT protein is related to the disease in the elderly and can be used as an anti-aging intervention.
